MOTOR STOP AND MOTION INDICATOR.

SPEOIFECATION forming part of Letters Patent No. 681,634, dated August27, 1901. Application filed January 14, 1901. Serial No. 43,140. (Nomodel.)

To all whom, it may concern:

Be it known that I, ARTHUR R. FORTIER, a citizen of the United States,and a resident of WVauwatosa, in the county of Milwaukee and State ofWisconsin, have invented certain new and useful Improvements in MotorStop and Motion Indicators; and I do hereby declare that the followingis a full, clear, and exact description thereof.

My invention has for its object to provide for automatic indication at adistance from a motor whether or not the same is active, and if so inwhat direction, said invention being especially designed for use on amarine vessel to indicate in the pilot-house thereof the direction ofmotion on the part of a propelling-engine or the fact that said enginehas been stopped. In view of the foregoing my invention consists in Whatis hereinafter particularly set forth with reference to the accompanyingdrawing and subsequently claimed.

The drawing is a diagram illustrating means in accordance with myinvention for automatic indication in the pilot-house of a marine vesselwhether a steam propelling-engine is stopped or running for ahead orastern.

Referring by letter to the drawing, A indicates a support for a cylinderB, containing a piston 0, having a rod D in connection therewith, thisrod being guided in a cylinder-head and a bracket 1), extendinglaterally from the support. Fast on the pistonrod .is an arm E,connected by a link F with a pointer G in pivotal connection with thesupport A to swing in the are of a circle, preferably arbitrarily markedby words or otherwise to designate direction of motion or stop of adistant motor according to the position of said pointer, such markingbeing herein shown on a segmental plate H, fast to said support back ofthe pointer. Spiral springs I l are arranged on the site directions fromthe arm E, one of these springs being compressible against bracket 1)aforesaid and the other against a gland c of the stuffing-box end of theaforesaid cylinder. An oil-cup d is shown in connection with thecylinder midway of its length, and by means of piping J J the ends ofsaid cylinder are connected with casings K K, containing valveshereinafter more particularly depiston-rod in opposcribed. A pipe Lcouples the Valve-casings, and a pipe M leads from casing K to acondenser or vacuum-chamber. The valve N in chamber K is an inverted cupengaged by a spiral spring P under compression in said chamber, and thestem N of this valve is shown in opposition to an arm Q, that is illustrated rigid on the stem Q of a steam-engine throttle-Valve; but saidarm may be made to operate with the start and stop mechanism of any typeof motor. The arm Q operates to push the valve N against resistance ofspring P when the motor is stopped, and conversely said spring operatesto move said valve in an opposite direction whensaid motor is started.

When operated upon by spring P, the valve N is caused to close air-portsin one end of easing K as well as to cut off the piping J J from saidcasing; but the reverse movement of said valve results in the opening ofsaid ports and piping, the pipes L M, previously open to the aforesaidcasing, being then cut off. Both ends of easing K are provided withair-ports, these ports and those of like kind pertaining to casing Kbeing preferably made in removable heads of said casings. Casing K has acentral reduction of bore between its unions with the piping J J, thisreduction of here being in communication with pipe L, and areciprocative stem R is provided with valves S S, that control thepassage of air or other fluid through said casing. The valve-stem R iscoupled to one end of a lever T, and a rod U in pivotal connection withthe other end of the lever extends through an eye in a lug e of a crankV in connection with a reverse-shaft W, constituting part of the engineaforesaid, a spiral spring f on the rod being interposed under pressurebetween said lug and a head 9 of said rod. By means of the rod andspring the connection between lever T and crank V will automaticallylengthen or shorten, as occasion may require, whereby proper seating ofeither valve S S is insured.

From the foregoing it will be readily understood that valves S S areautomatically set to close air-ports in one end of the casing Ksimultaneously with opening of like ports in the other end of saidcasing, and at the same time one terminal of the bore reduction in theaforesaid casing is opened and the other closed. As a result of this setof the valves S S and opening of the throttle-valve aforesaid air isexhausted from one end of cylinder B and admitted at the other end ofsaid cylinder, whereby the pointer G is automatically swung to aposition that indicates direction of motion on the part of the engine ofwhich said throttle valve constitutes a part, one of the springs I Ibeing then contracted and the other expanded. Now if the throttle-valvebe closed both ends of the cylinder B will be open to air, and owing tospring-pressure automatically exerted on piston '0 this piston will bemoved to the center of said cylinder, whereby the aforesaid pointer isswung in position to indicate Stop, this position of the pointer beingshown by dotted lines.

I have shown and particularly described my invention as an adjuncttoasteam-engine, especial reference being-had to the utilization of saidinvention for indicating in the pilothouse of a marine vessel when thepropellingengine is stopped or running for either ahead or astern; but,as heretofore intimated, said invention is applicable in conjunctionwith any type of motor and may be varied in detail to permit theutilization of fluid-pressure as the means for actuating the piston toswing the pointer by which the stop or direction of motion on the partof a motor is indicated. Hence I do not wish to be understood asconfining myself to what is herein specifically set forth. It is also tobe understood that my invention is just as applicable in conjunctionwith a one-way motor as with a reversible motor.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A cylinder, a piston in the cylinder, an arm fast on a rod connectedto the piston, a spiral spring compressible and expansible on the rodincidental to movement of the arm, a pivotal pointer linked to said arm,and means in conjunction with the start and stop mechanism of a motorfor exhausting fluid from either end of said cylinder simultaneouslywith its admission to the other end of same.

2. A cylinder, a piston in the cylinder, an arm fast on a rod connectedto the piston, spiral springs compressible on the rod in oppositedirections from the arm, a pivotal pointer linked to said arm, means inconjunction with the start and stop mechanism of a motor for exhaustingfluid from either end of said cylinder simultaneously with its admissionto the other end of same, and other means in conjunction with areverse-shaft of the motor for shifting direction of flow on the part ofsaid fluid with respect to the aforesaid cylinder.

3. A cylinder, a piston in the cylinder, an arm fast on a rod connectedto the piston, spiral springs compressible on the rod in oppositedirections from the arm, a pivotal pointer linked to said arm, aplurality of casings in pipe connection with each other and both ends ofsaid cylinder, one of the casings being organized for admission of airat but one end of same and the other casing made with air-inlets at bothends, avacuum-chamber pipe in connection with the first of said casings,a valve arrangedin said first casing to control the inlets and outletsof same, this Valve being provided with an exposed stem, a spring undercompression against the valve, an arm in conjunction with start and stopmechanism of a motor operative in one direction against said stem toactuate said valve against spring resistance, a stem in the second ofsaid casings, means whereby the latter stem is put into reciprocativeconnection with reverse mechanism of the motor, and a pair of valves onthe latter stem controlling the inlets and outlets of said secondcasing, whereby the direction of flow on the part of air with referenceto the aforesaid cylinder is made to accord with direction of motion onthe part of said motor.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Wisconsin, in thepresence of two Witnesses.

A. R. FORTIER.
